Mark Dever writes over at T4G a column on Togetherness. He writes:
The real front line is not between Calvinist evangelicals and Arminian evangelicals. It is between those who are lost in their sins and those who have been saved by God’s sheer grace in Christ. And this is not, of course, a war of flesh and blood, but a loving “assault” of sheep charging the wolves with the Good News of Jesus Christ, sheep who were themselves once at enmity with God. Our “weapons” to use the Biblical metaphor (Eph. 6:10-17), are spiritual. Here, on this real front line of conflicting worldviews and God-views, there is much togetherness in the Gospel by evangelical believers. 500 years ago Rome warned us that we Protestants would continue to split into countless groups, if we split with them over this. Well, 500 years of history have passed, and the verdict is in resoundingly. Rome was wrong. The Gospel is clear. Wherever we may mail our checks for missionary support, a Free Methodist evangelist in Brazil, an Assembly of God pastor in the Philippines, an Bible-believing Lutheran pastor in Ethiopia or a conservative Dutch Reformed Christian in South Africa, an evangelical Church of Scotland grandmother, a conservative Anglican in London, and a Southern Baptist deacon in Dallas, when they sit down next to someone on the bus or the plane, and share the Gospel with them, will all share the same Gospel–the good news about the Holy God who sent his Son to die and be raised for the justification of sinners. And that we experience God’s forgiveness and new life through faith alone in Christ alone. We don’t need a bishop in Rome or anywhere else to tell us this. We don’t need a world-wide organization. We just need the Holy Spirit, the Bible and the faithful teaching of this gospel by any one of thousands of congregations around the globe faithful to this gospel.
